Here are a few shots from the M8 with the Leica 28mm f/5.6 Summaron.
Some of the images are cropped a little.
Another lens from the fifties for my kit. Slow, maximum aperture is 5.6 but good contrast. Vignetting is 2.5 stops, according to Puts, and that looks about right from what I see. It is tiny, also.
So now I have two parallel kits for the M8: a retro kit with the 28mm Summaron, 50mm Summarit, & 85mm Summarex; and a more modern one with the Zeiss 25mm, Leica 35mm Cron verIV, & Leica 50mm Summilux pre-asph.
